I have 3+ computers running from one modem - hard ethernet and wifi iphones. My sons' phones drop out frequently requiring the modem to be restarted - but that does'nt bother me too much.Last night running fine.Booted up this morning sitting next to my wife who was happily browsing away.No go for me - even after several reboots.My computer seems to recognise the modem but refuses to logon.I also have LMDE installed on a 16GB flash drive and am running on that now - logged on and working fine. So it is not a hardware problem.Any ideas out there?

If the Modem shows up in Network-Manager great, other wise . . . I have to log out and boot into a LiveCD of any Mint/Debian OS-distro and 'set-up' a new connection.Then, I can log out of the LiveCD and Log-in to the installed LMDE.Usually, works fine after this ... and it does not drop the connection.

Here's another oneI use a cable connection and i always turn off my modem when i turn off my computer. When I start my computer and the modem synchronises and says everything is fine my network manager can't connect. I have to restart the modem and only then will the network manager connect. I don't know why this happens but it is stupid realy. If i try to let the computer boot and get the LMDE running and ready AND THEN press on my modem the same stupid thing happens.
